Bright, high-quality fluorescence
images.
The AX optical system attains the very
best brightness and assures crystal-
clear fluorescence images by
employing an improved numerical
aperture and high transmission
objectives and by incorporating a
100% optical path and high
transmission optics. The ideal mirror
unit for each application can be
selected from a range of 18. The
built-in illuminator accepts up to four
mirror units, allowing the user to
create the ideal combination for each
purpose or for a combination of
multiple observation methods. In
addition, the motorized excitation light
shutter also minimizes fluorescence
fading.
Impeccable phase-contrast
observation.
The AX Series features new phase-
contrast objectives employing an
optimally positioned innovative low-
reflection phase membrane.
Appropriate phase-contrast and
transmission are ensured for a wide
wavelength range for outstanding
contrast and image quality.
Nomarski DIC with higher contrast
and resolution.
Sophisticated manufacturing
technology and new multi-coatings for
the high-performance Universal
Apochromat objectives guarantee
superb optical performance for
fluorescence and Nomarski DIC
observations. Nomarski prisms
specially developed for Video
Enhanced Contrast and metallurgy
are also available.
Design algorithms suited for
polarized light observation.
The entire UIS optical system
including high-precision, strain-free
POL-objectives, condensers and
observation tube prisms has been
designed to minimize reflections from
lens surfaces and frame. Together
with dedicated Olympus optical
design algorithms, this ensures
unmatched image contrast for
polarized light observation. Used
with the Brace Koehler compensators,
these objectives allow high-sensitivity
examination of biological samples.
Live cell imaging.
The special correction of the
UPLAPO60
× WPSF objective renders
symmetrical image information from
planes above and below the focal
plane.
This imaging symmetry makes it the
objective of choice of digital
deconvolution applications. The
water immersion correction of the
objective eliminates spherical
aberration when imaging live material,
even when observing deep within a
cell
（ up to 250
µ
m ） . At the same time,
the objective's high numerical
aperture
（ N.A. 1.20 ） achieves
spectacular resolution.
